Confirming, I see this running Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1b1pre) Gecko/20080917020345 Minefield/3.1b1pre. Breakpad is: http://crash-stats.mozilla.com/report/index/a5e54d8f-84fb-11dd-bace-001a4bd43e5c

I get a slow-script dialog.  If I click Continue, I get a crash [@
js_ExecuteTree] before the script finishes.  I tested both mozilla-central and
tracemonkey branch.

Another page to test this crasher:
http://www.telkku.com/telkku
Click any link on that page and Minefield crashes every time, has been happening over a week now when Tracemoney enabled.

I no longer see this crash with Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1b2pre) Gecko/20081007 Minefield/3.1b2pre

If nobody else still crashes, I guess this is resolved.
